HEAT EXCHANGER
A poor quality steam source may cause a buildup of deposits on the heat
exchanger which will require periodic cleaning. After 2000 hours of
operation, remove a dispersion tube and check whether the heat exchanger is
coated with material deposits.
Material deposits can be removed from the heat exchanger with DriSteem’s
Humidifi er De-scaling Solution, available from your DriSteem representative. It
is the only cleaner/de-scaler approved for use with DriSteem humidifi ers. Use
of other cleaners/de-scalers may void your DriSteem warranty.
The Usage Instructions shipped with the DriSteem Humidifi er De-scaling
Solution contain important handling, mixing, timing, and pH testing
information.
The following additional instructions are for Ultra-sorb Model XV humidifi er:
1. If a float switch is installed:
– Note position of orientation mark (see Figure 31-1). Mark must be in
same position when fl oat switch is re-installed.
– Remove fl oat switch; the ½" NPT (DN15) port will be used to drain
header.
2. Install a ½" NPT thread drain hose in ½" NPT (DN15) port. After making
sure hose can reach a bucket or drain, elevate end of hose well above
connection.
3. Remove a dispersion tube, and add water to header to submerge heat
exchanger (see Figure 31-2).
4. Add 10 ounces of Humidifier De-scaling Solution per foot of header length
(30 mL of solution per 300 mm of header length). A 12-foot (3660 mm)
header requires about 1 gallon (3.8 litres) of solution.
5. After performing de-scaling procedure as described in Usage Instructions
and before resuming operation: Flush and drain header four times to
thoroughly remove Humidifier De-scaling Solution from system.
6. Re-install float switch in port.
